You can now buy my South Up, Aotearoa Centred, Equal-Earth Projection Map

I'm delighted to announce that I've actually finished a project!

Over the last few years, I've been designing a custom map. As per the credo of the "Organization of Cartographers for Social Equality", this map uses the Equal Earth projection to ensure proportional land-mass size, the South is at the up, and - of course - the globe has been rotated to 150°.

I've had it printed and I think it looks glorious!

Hanging on the wall

You can buy these maps from RedBubble.

Details

Buy

This is a large poster - I recommend buying the 120cm by 60cm version. It needs to be that size in order to make the country names legible. The cost per poster depends on your locale and whatever promotions RedBubble are doing.

These are not limited editions! I will print off as many as people order. Each one comes with a small inscription in the corner saying what the map is, and some other metadata.

As per below, you can download the assets in vector or raster format if you'd like to try printing them yourself.

Disclaimer

Maps are contentious. Some countries don't recognise other countries. Some borders are disputed. Some people clamour for reunification, some for secession. Some countries have a name given to them by their colonial oppressors. Some have been renamed by mad tyrants. Some countries have multiple names in different languages. Some are still fighting bloody wars in order to be recognised. Flags also suffer from the same problem.

The good news is that this is not an official map - my choices have no geopolitical consequences. The even better news is that the code behind the map is open source - so you can redraw it to your heart's content.

I have used the borders from Natural Earth, the country names from OpenStreetMap, and flags from Twemoji. If you dislike any of those, please direct your complaints to them.

Bugs

There are a few of things which have left me slightly dissatisfied.

By convention, most maps use Shaded Relief with the light coming from North-West. However, because this map is flipped, it cause an optical illusion which make mountains look like ravines and vice-versa. As noted:

Viewing images that do not conform to this convention may show a form of convex–concave ambiguity. Wikipedia page on "Top-Left" lighting

If you know how to redrawing or recalculate the shade, please let me know.

Secondly, in their default placement, country names and flags overlap. For example:

I manually adjusted the placement to keep labels and flags roughly in the right place without overlapping. I think I was accurate, but if you spot any mistakes - or know how to automate this - please let me know.

Non-Contiguous countries aren't handled well. For example, Alaska is unlabelled because it physically separated from the rest of the USA. The same is true of overseas territories like the Canary Islands and French Guiana.

The various seas, oceans, and other bodies of water aren't labelled.

I'm sure you will spot a few other errors. Either leave a comment here or raise an issue on GitHub.

How

This was a multi-stage process - mostly involving R.

Background

The background image comes from "Color terrain art without type halos". It's a TIFF which has been rotated and converted to PNG.
